Abstract: Poly[1-(trimethylsilyl)-1-propyne] membranes were modified with fluorine gas. The fluorinated membranes exhibited good gas permeation properties and a significant increase in gas selectivity over the unfluorinated PTMSP membranes.The oxygen-nitrogen separation coefficient αo2/N2 increased from 1.5 to 4.75,the oxygen permeation coefficients Po2 decreased from 8600 to 370 barrier, and the constancy of gas permeabitily of the membranes was improved.
Key words: polytrimethylsilylpropyne, modification by fluorine, oxygen nitrogen permeability
